Abstract
This paper presents the chronological development of Gulf of Suez Petroleum Co. (GUPCO) offshore well completions. Reservoir depletion and the problems experienced with the initial completions prompted the need for basic changes. Several changes in completion systems were studied before an optimum solution was selected. The development includes all the areas of original completions that had shown operational shortcomings: the completion-fluids design and selection, down hole equipment, running and pulling operations, wireline phase, perforating, and initial flow phase. All the changes interacted and resulted in the completion optimization which have considerably reduced operations time and cost, significantly reduced operational problems, and increased well productivity. It worth to note that, as a result of completion optimization, now a completion job takes less than one half of the time that was spent to complete one well ten years ago.
